On-Screen Keyboard uses only buttons from Q-i, numbers 23 567 - so other buttons are locked, esspecialy modifiers. PLS Unlock !modifiers!
Use all others leters buttons:
high octave: Q-i
Middle Octave: A-L
Lower Octave: Z-M
Add some kind of MODES & Tonality for ex. i choose D Dorian - and all buttons will be in key
This changes very helps when working with laptop
